WRITE • PHRASES of 16 steps hold notes, chords, instrument, velocity and effects; they stack into CHAINS, and chains arrange into a twelve-channel SONG • Hold a cell and slide to set a note or a value — it plays as you go • Select, copy and paste cell by cell, transpose whole sections, and end a note exactly where you want with OFF • Every channel loops on its own and can run at its own tempo, locked to one clock • A hardware keyboard on iPad and Mac, a MIDI keyboard, or any Bluetooth game controller drives the whole tracker SOUND • Over 450 ready-made sounds sorted by what they are — drums, bass, keys, bells, plucked, strings, winds, voice, leads, pads, fx — each one a tap away from playing, all balanced to the same loudness. Save your own for any engine • DRUM KIT: ten drum slots in one instrument — eight built-in kits, or build your own from any sound or sample • Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable and the dual-oscillator MODX, plus DRUM, an analog drum voice • WOVEN, a macro-oscillator with 24 models and 96 classic DX7 patches; ROUND, a resonator for strings, bars and bells; MODAL for struck percussion • SAMPLER: record or import, chop at transients, stretch to the tempo, loop, reverse, round-robin • SPEECH sings your lyrics in English and Japanese; GRAIN turns any recording into clouds; DRONE, RESONATOR and TEXTURE build ambient beds • AUv3 hosting: play your instrument plug-ins and insert effect plug-ins on any channel SHAPE • 32 effects on any note: delays, reverbs up to thirty seconds, tempo-synced gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps, FOGGY granular clouds and more • AUT automation morphs an instrument and its effect across the rows • RANDOM dice, tables for instant arpeggios, a groove editor per instrument, scale lock • A twelve-channel mixer with volume, pan, mute, solo and plug-in inserts PERFORM • LIVE MODE: launch phrases from six scenes on pads, quantized to the beat or the bar, and punch in delay and filters — or latch them CONNECT • MIDI in with step and live recording, MIDI out to hardware, MIDI clock and Ableton Link KEEP • Render to WAV (16 or 24 bit), stems and MIDI; share songs as files; your session autosaves • A lock-screen player with cover art in your theme • 28 themes — the studio look comes in dark and light and can follow your device — a theme editor, seven typefaces, hex numbers if you like • English and Japanese, and a demo song to start from Everything runs on your device.

StepLoom is a fast, touch-first electronic music sketchpad for making beats, loops, basslines, and melody ideas on iPhone and iPad. It gives you the focus of a compact groovebox without the weight of a full DAW, so you can start a rhythm, shape a synth line, try an AUv3 instrument, arrange patterns, and keep moving while the idea is fresh. Create drum patterns with a step sequencer, write melodic parts with piano-roll style editing, stack chords, add legato, adjust BPM, mix tracks, and switch sounds. Add Sample tracks by importing audio or recording directly in the Tracks view, then use the waveform editor to trim, reverse, normalize, tune, and shape One-shot or Loop playback. The project Media Library keeps custom audio available for reuse and arrangement. Turn loops into songs with three complementary arrangement views: shape Patterns and audio clips on the Timeline, launch quantized Patterns and Scenes in Session, or build visual paths and probability rules in Flow. Draw or record automation for mixer controls and supported AUv3 parameters. When you want to go beyond the built-in sounds, add AUv3 instrument or effect plugins, choose exposed plugin presets, open compatible plugin interfaces, and activate Plugin Sound directly from the sound picker. Optional iCloud sync keeps compatible projects and project media available across your Apple devices. StepLoom continues to work locally when sync is disabled. StepLoom is built for quick electronic music drafts: open the app, tap a grid, hear the result, and turn a loop into a structured idea. Main features: - Touch-friendly beat and melody workflow - Drum, melody, and custom Sample tracks - Step sequencer with playback highlight and loop control - Piano-roll style melody editing with chords and legato - Audio import and microphone sample recording - Waveform sample editor with trim, reverse, normalize, gain, tuning, One-shot, and Loop controls - Project Media Library for reusable custom audio - Timeline editing with drag, resize, layers, sections, loop ranges, and multi-selection - Quantized Pattern and Scene launching with Session performance recording - Blueprint-style Flow rules with Next, Jump, Random, Stop, and probability - AUv3 instrument and effect plugin slots - Plugin preset reading for AUv3s that expose factory presets - Plugin Sound option for playing tracks through AUv3 instruments - Mixer and AUv3 parameter automation - Mixer controls for volume, pan, EQ, filter, drive, meters, master gain, and limiter - MIDI input and external clock sync options - Optional iCloud project and media synchronization - Export full songs or the current pattern as audio, stems, or MIDI - Adaptive iPhone and iPad layouts StepLoom is for producers, beatmakers, songwriters, and electronic music learners who want a focused place to capture musical ideas before moving into a larger DAW.
